OLS449

Overview

The OLS449 is a dual-channel, radiation-tolerant phototransistor optocoupler manufactured by Skyworks Solutions Inc. It features a hermetic surface-mount LCC-8 package designed for high-reliability applications in gamma, neutron, and proton radiation environments. The device provides electrical isolation between an LED input and N-P-N silicon phototransistor output. Key specifications include a minimum collector-emitter breakdown voltage (BV CEO) of 65V and 1500 V DC electrical isolation. It guarantees a high current transfer ratio (CTR) over an ambient temperature range of -55 °C to +100 °C, with optimized performance at low LED currents.

Feature Summary

Radiation tolerant construction suitable for harsh environments
Hermetic surface mount packaging for high reliability
Dual channel configuration with high current transfer ratio
High collector-emitter breakdown voltage

Applications

Gamma radiation detection systems
Neutron monitoring equipment
Proton radiation environment interfaces
High-reliability aerospace electronics

Procurement Notes

Verify the specific lot screening requirements and radiation tolerance certificates directly with the manufacturer or authorized distributors. Confirm that the hermetic seal integrity meets the project's environmental standards. Ensure the operating temperature range aligns with the guaranteed CTR specifications provided in the official datasheet.

Selection Notes

Select this component when radiation hardness and hermetic sealing are critical design constraints. Compare the guaranteed CTR degradation characteristics against standard alternatives like the JEDEC registered 4N49U to ensure sufficient margin for long-term reliability in ionizing radiation fields.

Part Context

The OLS449 belongs to the Isolink family of radiation-hardened optocouplers. It shares processing similarities with the OLS049 but offers enhanced current transfer ratio performance. This series is engineered specifically for military and space applications where standard commercial components would fail due to radiation-induced latch-up or parameter drift.
